Pretty sure lots of people use blue tape and it works fine.

There are several threads on masking, if you do a search of the forum. Here’s one:

Laser masking

I am fairly new to lasers. I started using them in the past year, I am currently using a Gravograph LS900 60w laser available at my work and was wondering what kind of masking will work the best for lasers. I have used basic masking tape as well as paper transfer paper that my wife uses on her sillouhete vinyl cutter. None of it works well and the laser dosnt seem to penetrate it very well, however I can engrave into hardwood at 50% power and 80% speed down to almost a 1/4 of an inch. Can anyone…
